Claims priority, application Italy November 27, 1950 Claims. -1 Pressesfor macaroni manufacture are 'pro vided with rounddie plates and in themore mod ern types with die plateshaving an-elongated shape.

fThough in the following description only the 7 term die plate will beused, it'is understoodt-hat the invention is equally well applied toround-and to elongated die plates.

,A serious inconvenience that should be rectified in all types of dieplates is that the length of, the macaroni strands, coming out'from-thevarious holes of the die plate is not uniform, asfrom one hole a. longermacaroni strand may emerge than from another. As the macaroni strandsobtained in'this way must later, fortechn-ical and com mercial purposes,be reduced to the same length, it is necessary to cut the'strands whichare longer. This is an operation which, besides causing-a waste of timeandlabor, also causes a certain loss of alimentary paste.

Various-attempts have been made to --eliminate thisinconvenience,-without coming to a satisfactory result.

"The-object of the present invention isa-die plate which fully avoidsthis inconvenience.

The die plate whichunay be of: a round or of an elongated shape, ischaracterized by including adjustableelements which go through it andproject-in-varying degrees in the direction of the chamber which feedsthe alimentary paste into the press, each of these 4 adjustable elementsserving-to control the flow of the macaronipaste in a zone of the dieplate or iii-relation to agroup of holes in the die plate.

The die plate according to the 1 invention is further preferablycharacterized by thefact that above the die plate itself are disposedone or more passing chambers for the paste, so that the variableprojection of the adjustable elements in the chamber or-chambers willassure a uniform passing of the paste through the various holes, relative to the element and to the chamber which is in connectionwiththehead conduit or with a branch conduit of the head conduit, alongwhichthe press impels the paste.

:In a preferred embodiment the round vdie plate of a press for macaronimanufacture according to the invention is characterized .b the factthatthe holes for thezpassage of the paste are: grouped around therespectivead-justable element.

In -.a preferred embodiment the elongated 'die plate for macaroni in amacaroni manufacturing machine according to the invention ischaracterized by the fact that the holes for the passing of the pasteare divided-in groups, each group being provided with its own adjustableelement and therrariouslgroup being arran ed in the1onsi tudinaldirection ofthe elongated plate.

In thislast embodiment the die plate is characterized by cooperatingwith theplate above it.

and is provided with as many passingchambers as there are adjustableelements, also with an upper longitudinal conduit, connected --to saidchambers, and substantially fed in onev intermediate point by thearrival of the pasteemitted by the press, this direct conduitbeing openon-lts two ends where it is provided withclosure plugs to be removed forcleaning.

In the annexed'drawing theinvention is shown by way of example,inseveral of its embodiments:

Fig. l is a longitudinal section'talren along the plane 1-1 of Figures2, 3 and l, of an elongated olieplateappliedto a screwpress of aconventional-type.

Fig. 2 shows, with someelements removed,-a section taken along theplaneII-Jlof Fig; 1.

Fig. '3- shows a view from the bottom in thedirection of the arrowIIL-of the-elongated die plate.

Fig. a shows a plan View of the end ofthepress and of-the elongated dieplate-inthe direction of the arrow IV.

Fig. 5 shows the details of the connection of the die'plate andthecounterdie plate-of elongated shape, being a partial sectional viewtaken along the plane V-V of Fig. 1.

Fig. 6 shows-a section tak-enalong the plane VIVI of Fig. 7 of the headof a presswith a circular die plate and with a counterdie plate, alldiagrammatically shown.

Fig.7 shows the die plate asseen in triadirection of the arrow VII (Fig.6).

The end block 1 of the press provides the con.- duit 2 along whichthescrew of the. press pushes the .paste towards the die plate. Saidconduit is connected (Fig. 1) witha transverse conduit provided withspaced holes i. Underneaththe conduit 3 a. guide .5 inthe shape of achannel is disposed andhas the, same number. of holes 6 which willregister. coaxially with. the said holes 4. In the channel shaped guide.5 the ledges-l are disposed and these are designed to house. thecounterdie plate 8 whichlwi-ll be pushed. into. the guide 5, in thedirection-of the arrow 9. The-die plate it itself will consequently bedisposed under the counterdie plate 3: andiwill rest enthe g surfacesand theuledgesfi. In order-to avoid placing of the die plate it and thecounterplate 8 in the direction of the arrows, the endsofethe guide 5have side swellings i in which thescrews i2 which secure theend plate isare screwed; this structure being provided for each endofthe die plate.Corresponding to the above mentioned holes a and 6, the counterplate-thas the same number of holes M which are -'designed to connect theconduit 3 with thechambe-rs it disposed in I the counterdieplate; saidchambers are substantially enlarged ontheir rim towards the die; plateand, corresponding-tothe larger dimensions of said chambers there are,on, the die plate the holes it for the passing of the macaroni. In theillustrated embodiment, said holes are disposed around a threaded holein which the threaded adjusting element I! is screwed. The end it ofthis element penetrates to a variable extent, according to itsadjustment, into the chamber Ill. The rectilinear conduit 3, is open atits two ends on which the screwed plugs it are applied. When they areremoved it is possible to enter directly into the inside of the conduit3. The entire above mentioned group is mounted in an easily removableway to the head I by means of the pivot Ell, the plate ii, thecounterplate 22 and the bolt 23 mounted on a pivot 24 and Controlled bymeans of the lever nut 25. The entire assembly is covered with the usualjacket or housing 26 for the passage of a heat transfer liquid tomaintain the alimentary paste at the desired temperature.

The operation of the device is as follows: If the die plate Ill withoutthe adjusting elements 11 and without the counterplate 8, would bedirectly connected to the conduit 3 so that the paste that passes to itwould be forced to go through to holes IE to form threads, it would beobserved that, due to many causes such as: deviating of the flow of thepaste, change of temperature and therefore of speed of the paste,varying friction in the Various zones, etc., the threads of the macaroniwhich emerge from the holes It would have perceptibly different lengthsas occurs in the well known elongated die plates.

Instead, according to th invention, by adjusting with care one by onethe elements II, that is to say by varying the capacity of each chamberl5, or by moving to various positions their heads I8 with respect to thearrival opening 14 of the paste, the above mentioned conditions arecontrolled in such manner that, through each of the holes of the dieplate it, the macaroni will pass at exactly the same speed, so that thelength of the threaded paste will be absolutely the same along the wholeof the die plate H3.

With particular reference to Figs. 6 and 7 there is in 2? the usualarrival chamber of the paste in the head 28 of a press with circular dieplate (only diagrammatically shown). In this embodiment there are thesame features of construction before mentioned and they are providedwith the same reference characters as those before used.

For a circular die plate the operation is as above described, obtainingthe desired uniformity of flow of the macaroni through the conduits [6by means of suitable adjustment of each ele ment [1.

Though, for illustrative purposes the present invention has been basedon what is above described and shown, many changes and modifications maybe made in the embodiments of the invention, all based on thefundamental idea of the same as set forth in the following claims.
